  In the shower head of Patent Document 1, the front surface of the face is formed flat, and a water spout is opened on the front surface. And the outer peripheral part of the face front surface in which the inclined watering port is located is inclined so that it may recede toward the outer peripheral side. For this reason, the opening surface of the water spout is also inclined outward, the shower is discharged outward, and the water discharge range is expanded.

  Here, when a plurality of protrusions are arranged on the front surface of the face, a water spout is opened at the protrusion of the protrusion, the shower water discharge direction is inclined outward, and the protrusion surface is inclined accordingly. The inclined surface is conspicuous and the appearance is deteriorated. In order to avoid this, when the projecting end face of each projecting part is located on the same plane, the edge part on the outer peripheral side of the face in the water spout protrudes from the edge part on the inner peripheral side. For this reason, the hot water discharged toward the outside may be blocked by the outer peripheral edge of the water spout, and the spread of the water discharged may be hindered or the water discharged may be scattered.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a shower head capable of obtaining a good appearance.

In the shower head, the protruding end surface of the projecting portion has a recess, the water spout is disposed on the bottom surface of the recess, the shower channel is inclined, and the bottom surface of the recess is The shower channel is inclined so as to recede toward the inclined direction side.

  According to this structure, even if the shower channel is inclined and the water spray port is opened at the protruding end of the protrusion, the recess is inclined so that the bottom surface of the recess is retracted toward the inclined direction side of the shower channel. Since the edge portion on the side of the inclination direction is retreated, water can be discharged without being disturbed in the inclination direction from the water spout. And since the inclined surface of a protrusion part is located in a recessed part, the fall of the external appearance of each protrusion part can be suppressed. Therefore, good design properties can be obtained as a shower head.

  As shown in FIG. 3, an inner pipe 15 that forms a water passage is incorporated in the housing 14 of the grip portion 12. A shower hose (not shown) is connected to the base end of the inner pipe 15. The water sprinkling unit 13 is connected to the tip of the inner pipe 15.

  As shown in FIGS. 2 and 3, the watering unit 13 includes a back cover 21, a face frame 22 positioned on the front surface of the back cover 21, a face plate 24 attached to the front surface of the face frame 22, and its face A watering plate 25 attached to the front surface of the plate 24 and an inner face 26 attached to the front surface of the watering plate 25 are provided. An outer face 27 is detachably attached to the front side of the watering unit 13. The face frame 22, the face plate 24, and the inner face 26 are made of a hard synthetic resin material, and the water spray plate 25 is made of a synthetic rubber material that is softer than the face frame 22, the face plate 24, and the inner face 26. . The outer face 27 is made of a synthetic rubber material that is softer than the watering plate 25.

A flow path 31 is formed between the front and back surfaces and the outer peripheral surface of the face plate 24 and the face frame 22 and the water spray plate 25.
As shown in FIGS. 1 to 3, the watering plate 25 is integrally formed with watering nozzles 251 as a plurality of projecting portions and arranged at equal intervals in the vertical and horizontal directions. The water spray nozzle 251 passes through the holes 261 and 271 of the inner face 26 and the outer face 27, and the tip portion protrudes forward. As shown in FIG. 4, each water spray nozzle 251 is provided with a shower channel 253, and a water spray port 252 at the tip of the water spray nozzle 251 opens at the protruding end of the water spray nozzle 251. Then, hot water from the shower hose passes through the inner pipe 15, passes through the shower channel 253, and is discharged as a shower from the water spray port 252 of the water spray nozzle 251.

Hereinafter, the shape of each watering nozzle 251 will be described in detail.
As shown in FIG. 4, each water spray nozzle 251 and each shower channel 253 extends in a direction along the center line L of the rectangular shower water discharge range AR, and is located on the center line L side of the shower water discharge range AR. Except for 251 and the shower channel 253, the sprinkler port 252 side is formed in a tapered shape. In this embodiment, the watering nozzle 251 and the shower channel 253 located on the center line L side extend in parallel with the center line L, and the watering nozzle 251 and the shower channel 253 on the outer peripheral side are obliquely outside the shower water discharge range AR. It is tilted so as to be oriented toward the direction.

  And the outer side of the outer peripheral surface of each water spray nozzle 251 on the outer peripheral side and the outer side of the inner surface of each shower channel 253 on the outer peripheral side extend in parallel with the center line L. Further, the center line L side of the outer peripheral surface of each water spray nozzle 251 on the outer peripheral side and the center line L side of the inner surface of each shower channel 253 on the outer peripheral side are directed obliquely outward of the shower water discharge range AR. It is inclined. And the water spray nozzle 251 located on the outer side of the shower water discharge area AR has a larger inclination angle of the outer peripheral surface on the center line L side, and the shower channel 253 located on the outer side of the shower water discharge area AR. The inclination angle of the inner surface on the center line L side is large (α1 <α2 <α3 <α4). Therefore, in the present embodiment, the water spray nozzle 251 and the shower channel 253 located on the outer side of the shower water discharge range AR have a larger inclination angle outward.

  The protruding end surface 254 of the watering nozzle 251 is provided with a recess 256 having the bottom surface 255 as the periphery of the watering port 252. The bottom surface 255 of the recess 256 is inclined so as to recede toward the outer side with respect to a surface orthogonal to the center line M of the shower channel 253. Accordingly, the bottom surface 255 is inclined with respect to the surface orthogonal to the center line L so as to recede toward the outer side. And the inclination | tilt angle of the bottom face 255 of such a recessed part 256 is an angle larger as the recessed part 256 of the watering nozzle 251 arrange | positioned on the outward side ((beta) 1 <(beta) 2 <(beta) 3 <(beta) 4). The protruding end surface 254 of each water spray nozzle 251 is formed on the same plane orthogonal to the center line L.

The operational effects exhibited by the above embodiment will be collectively described below.
(1) The protruding end surface 254 of the water spray nozzle 251 is provided with a recess 256 having a bottom surface 255 as the periphery of the water spray port 252, and the bottom surface 255 of the recess 256 is outside the surface perpendicular to the center line L. It is inclined so as to recede toward the side.

  In such a structure, since the opening direction of the water spray port 252 of the shower channel 253 can be inclined outward with respect to the center line L of the shower water discharge range AR, the water discharge direction of the hot water from the water spray port 252 is inclined outward. Thus, the shower water discharge range AR can be expanded. Therefore, hot water can be discharged over a wide range. Moreover, in order to diffuse hot water over a wide range, although the recess 256 having the inclined bottom surface 255 is formed on the protruding end surface 254 of the watering nozzle 251, the protruding end surface 254 is located on the same plane. The appearance can be aligned. Accordingly, it is possible to obtain a good design property by suppressing the deterioration of the appearance of the watering nozzle 251. That is, since the protruding end surface 254 of each watering nozzle 251 can be in the same plane position regardless of the inclination angle of the bottom surface 255 of the recess 256 in order to determine the water discharge direction, high design characteristics are achieved. Can be obtained.

  Moreover, since the bottom surface 255 of the recess 256 is inclined in the inclination direction of the shower channel 253 so as to recede toward the outer side of the shower water discharge range AR, the outer side of the shower water discharge range AR of the water spout 252 The edges of the are retracted. Therefore, the water discharged from the water spout 252 becomes a shower with almost no obstruction by the edge of the water spout 252. Therefore, even if the shower water discharge range AR is greatly expanded, shower water discharge without disturbing the flow becomes possible.

(2) The outward inclination angle with respect to the center line L is greater in the shower channel 253 arranged on the outer side. Therefore, the shower water discharge range AR can be expanded.
(3) Each shower channel 253 is formed in a tapered shape that becomes thinner toward the water spout 252 side. For this reason, the flow rate of the hot water inside the shower channel 253 can be increased, and hot water can be discharged from each water spout 252 vigorously.

  (4) A portion extending substantially parallel to the center line L is formed on the outer side of the outer peripheral surface of each watering nozzle 251 and on the outer side of the inner surface of each shower channel 253. As a result, when the water spray plate 25 is molded using a mold, the mold can be released without difficulty, so there is no need to form the molding surface of the mold with a movable core. The configuration of the mold can be simplified and the durability of the mold can be improved.

  (5) Each water spray nozzle 251 is formed in the taper shape which the water spout 252 side becomes thin. Therefore, when the shower head 11 is assembled, the watering nozzle 251 can be easily inserted into the hole 261 of the inner face 26 and the hole 271 of the outer face 27, and the assembly is simplified. Moreover, since the watering nozzle 251 is harder than the outer face 27, the watering nozzle 251 is not easily deformed when the watering nozzle 251 is inserted into the hole 271 of the outer face 27. Therefore, the shower can be discharged in the intended direction along the protruding direction of the watering nozzle 251 and the splash of hot water can be suppressed.

  (6) The inclination angle of the bottom surface 255 of each recess 256 is larger as the watering nozzle 251 disposed on the outer side. Thereby, since the water discharge direction can be inclined outward as the water spout 252 is arranged on the outer side, the shower water discharge range AR can be expanded.

(Example of change)
It should be noted that the above embodiment can be modified as follows.
The shower channel 253 on the outer side of the shower water discharge range AR is not tapered but has a shape that extends linearly with the same cross-sectional shape.

  -Arrangement | positioning of each watering nozzle 251 in the outer surface 27 outer surface arbitrarily is changed arbitrarily. In such a configuration, when the shower water discharge range is a circle, an ellipse, a substantially regular polygonal shape, or the like, the symmetry axis of the shape can be the center line of the shower water discharge range. In addition, when the shower water discharge range has a line-symmetric shape or an asymmetric shape, the center of gravity position or the central portion of the shape can be the center line of the shower water discharge range.

The inclination angle of the bottom surface 255 of each recess 256 is set to an angle orthogonal to the center line M of the shower channel 253.
In the above-described embodiment, the shower water discharge range AR is widened by inclining outward toward the shower flow channel 253 on the outer side of the shower water discharge range AR. For example, the shower flow channel 253 faces the center line L direction. Changing the inclination direction of the shower channel 253 as appropriate, for example, inwardly or in the circumferential direction of a circle centered on the center line L.

-The watering plate 25 and the outer face 27 are formed of a hard synthetic resin material.
-At least one of the face frame 22, the face plate 24, the water spray plate 25, the inner face 26, and the outer face 27 is formed of a metal material.
